A structure of customized web services includes a document format related to web services, a description document of provided services, and definitions of operation and communication methods. The customized web services structure contains: a services searching exhibitor, which is built upon a basic program code to provide the standards for registration in the basic program code structure and searching the web services; a services provider, which uses the web services defined by the basic program code structure and shows the contents in the services searching exhibitor for searching; and a services requester, which makes use of the basic program code structure. The basic program code is one of the non-XML type Vc, Vb or C# programming codes of high compatibility.
